A New Fault Detection Device for Distribution Automation

Abstract

The invention discloses a novel distribution automation fault detection apparatus, including a relay 1, a relay 2, an intermediate relay 1, an intermediate relay 2, a button switch 1, a button switch 2, a button switch 3, a positive pole power output end, a negative pole power output end, a negative pole power wiring terminal, an intermediate wiring terminal, a switch-on indicating lamp, an energy storage indicating lamp, and a switch-off indicating lamp. The apparatus is connected with a 10kV automation terminal. When the 10kV automation terminal is subjected to remote-controlled switching on and off, an analog switch correctly displays switching on and off states controlled by the terminal and feeds back the switching on and off states to a remote control system, and distribution automation fault positions are effectively screened, and thus defects of remote control of distribution secondary equipment are effectively reduced, and the reliability of power supply is improved.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to a novel power distribution automation fault detection device. Background technique [0002] With the comprehensive intelligent transformation of the 10kV distribution network, excellent results have been achieved in terms of rapid isolation of faults and rapid restoration of power supply in non-faulty areas. However, the refusal of switches still plagues the current distribution network problem. The direct problem caused by such defects as switch refusal is that when a fault occurs, the fault area is expanded, resulting in a power outage in the non-fault area, thereby reducing the quality of power supply. [0003] When eliminating defects such as switch refusal, it can be judged whether the switch refusal is caused by the failure of the switch body or the failure of the controller without power failure. If it is caused by the failure of the controller, the controller can be repl...

[0004] But how to judge whether it is the fault of the switch body or the fault of the controller, it is the most inadvisable to conduct a test judgment when the switch is charged, which will not only cause multiple power outages on the line, but also pose a huge safety hazard
